IMPRVEMENT IN CEURNS.

y The Schedule referred to in thse Letters Patent and making part of the same.

. the art or science to which it most nearly appertains,

to make and use my said invention or improvements without further invention or experiment.

The object of my invention is to-provide an improved device for the purpose of converting cream into butter,

whichI term a reaction-churm Yand Y It consists in sov arranging the driving-gear` that the agitators will be moved once around and back alternately, producing a reaction, which will quickly convert the cream into butter. l

On the top of the cover are two projecting standards, opposite each other.

A shalt, which is operated by a crank at one end, passes across these standards, having its bearings on their tops. y

This shaft carries, near -its centre, two partiallycogged wheels, which gear, alternately, with a pinion placed between them, which gives auv alternate rotary motion to the agitators in the churn.

The shaft which carries the agitators is connected to the pinion-shait by a square coupling, so that it may be'taken oli', when desired.

Air is admitted' to the'interior of the churn through the pinion-shaft, agitator-shaft, and arms, whichare hollow.

To more fully explain my invention, reference is had to the accompanying drawings, and letters marked thereon, forming a part of thisspecication, of which- Figure -1 is a side sectional view of my invention.

Figure 2 is a side view, showing one of the wheels.

A is achurn, of the ordinary construction, which is provided with a cover, B.

Two nplightstandards, D D, are placed at each side oi" the cover, opposite each other.

A shaft, E, carrying two partially-cogged bevelwheels, F F, has its bearings on thertop of the varms D D, and is 'driven by a crank, G. Y

A pinion, H, turning on an upright shaft, I, which ,passes down through the cover, is placed between the Vwheels F F, which,fbeing provided with cogs only on one side, engage the pinion alternately, moving it in one direction entirely around, and then in the other,

zwithout reversing the direction of the driving-shaft.

The agitators consist of two wings or floats, a a, ab tached to a spindle, J, by means of arms l1 b.

The spindle J h'as its step in the bottom of the churn, the upperv end being attached to the pinion-sha; I by means of a square coupling at c. Y

The pinion-shaft I, spindle J, and arms b bare hollow, .in order to admit the air into the milk during the process of churning. v

By the use of this device, a churning can be done in a very short time, with very little labor, the peciiliar motion of the agitators tending to keep the cream in a constant state of ebullition. I

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, s

In combination with the partially-cogged gear-wheels F F and hollow pinionH, the agitator, composed of Witnesses J. L. BOONE,

GEO'. H. STRONG.

I'have hereunto set my hand'
